title: Reaction of cyclic α-oxoketene dithioacetals with methylene isocyanides: a novel pyrrole annulation-ring-expansion domino process.
abstract: The title reaction provides a direct entry to a range of biologically relevant annulated pyrroles via a domino process involving a regioselective one-carbon homologation of cyclic ketones as the key step.
